Application filed. November 28, 1927. seria ivo. 236,221.

The invention relates to an improvement in gas burners somewhat similar to that disclosed in my prior Patent No. 1,575,653, March 9, 1926. The present burner will epcrate more successfully on low pressure gas than do other burners of this type. Gas pressures of 15 to 20 pounds are quite usual in in dustrial applications, while in domestic uses, the pressures may vary as low as four ounces.

The present invention relates primarily to an improvement in the jet and the spiral formed element above the jet and its application to prior burner constructions.

In the drawings, Fig. 1 is a plan view of the [5 burner. Fig. 2 is a side view of the burner. Fig. 3 is an end view of Fig. 2. Fig. 4' is a sectional view of the burner, taken along the line IVIV in Fig. 1. Fig. 5 is a view taken along the line V-V, Fig. 4; while Fig. 6 is a view taken along the line VIVI of the same figure. Fig. 7 is an enlarged plan view of the jet. Fig. 8 is a sectional view taken along the line VIIIV1II, Fig. 7. Fig. 9 is a bottom view of Fig. 7. Similar numerals 25 of reference indicate corresponding parts throughout all the figures of the drawings.

Referring to the drawings;'at 10 is the gas intake leading to the manifold 11 included between the end brackets 12, 13 which sup- 80 ports the box-like base unit having four sides 14, 14, 14", 14 and a base 15. Cast 1ntegral with the base 15 is the tubular element B which registers over the jet 16 in the threaded plug 17 which screws into the proper point in the top of the manifold 11 for this purpose. In other applications a straight hole was punched or drilled through the manifold which generally left a ragged edge on the bottom of the hole, while this ragged edge together with the straight hole provided a friction surface which retarded the flow of low pressure gas. It will be noted that the plug 17 has a tapered interior at 16 which does not interfere with the flow of low pressure gas or so that the gas is speedily discharged into the tube B through the jet 16. It will be noted that the base of the tube B is flared somewhat more than the portion immediately above it and then the tube again enlarges more and more towards the top. The base of the tube B extends below the base 15 a small distance while the top of the tube B extends a considerable distance above the base 15.

The top cover of the box 14 is an inverted box having four side elements 18, 19, 20, 21,

I or bore.

each cut away as at 22 as gas ports and the corners such as 23 thus formed act as legs resting on the'base 15 as support for the in verted box. The top of'this box has a central pan like cover 24 upon the under side of which is formed a spirally ribbed element or rosette which registers above the flared upper end of the tube B. This element has a plurality of spirally fashioned ribs such as 25 alternating with depressions 26 as illustrated. This rosette as seen in Fig. 4 is of about the same diameter as the outlet of the tube B and depending as it does over such outlet, the spiral ribs in efiect provide spiral conduits leading upwardly towards the under surface of the cover 24. Cracks such as 27,28, 29 and 30 occur between the corners of the inverted box element as slots for gas ports.

The gas as received into the chamber 11 passes very readily through the space 16 and out of the orifice 16 where it mixes with air before entering the flared base of the tube B. The size of the hole- 16 to accommodate various requirements may be changed by using a larger plug or a small plug as desired or so that the orifice 16 may be of the desired size. The gas passing up the increasingly enlarging bore of the tube B gains speed and strikes the member A under speed conditions or so that the spiral ribs 25 occasion a whirling condition to the incoming gas while still rising which mixes the gas and air in much better manner than in former designs. The inner bore of the tube B is likewise of great importance since it helps speed up the gas over a tube of constant tubular cross-section The gas then passes downwardly on the outside of the tube B then through openings'such as 22 and out through the slots 2730 for ignition and gas burner purposes. or The clamps 31, 32 serve to interlock with lugs such as 33, 34 on a companion burner for group assemblage as in my prior designs.

Such modifications may be employed as lie within the scope of the appended claims.

Having fully disclosed my invention what I new claim as new and desire to secure by Let ters Patent is:

1. In gas burners, a box-like element including four side members and a bottom mem 105 her; a tubular element integral with and vertically arranged as a part of the bottom memher and extending more above than below said bottom; a cover element having a depressed central portion and upwardly and outwardly m) 5 ment, openings intermediate said corner edge portlons and slots lntermediate the coverand the upper edges of the first element; and a spirally ribbed member integral with and depending from the under side of said cover ar- 10 ranged above the tubular element.

2. In gas burners as described in claim 1, a gas jet below thetubular element. '3, In gas burners as described in claim 1, a gas jet belowthe tubular element including a plug fashioned as athreaded screw and hav- 15 ing a'tapercd interior leading to a gas orifice and positioned beneath the tubularpelement. In testimony whereof I aflix my signature.
